We're reducing prices!

1.1.2024

Dear customers, we have optimized our production processes and input costs, which is why we were able to reduce the final prices compared to the 2023 price list by up to 20%! If you are our partner (installation company, wholesaler), you will find the new prices after logging into your account. On the My account page, click on the link Your current price list. If you are not our partner, the final prices listed in the Direct purchase section apply to you.

End of rationing system

1.9.2023

Dear customers, due to the availability of parts for production, we are stopping the rationing system for all products supplied by us from September 1, 2023. All products are now in sufficient quantities in stock.

Rationing system

8.1.2023

Dear customers, due to the high demand, we are introducing a rationing system for our most ordered products from 9 January 2023. For more information about this method of purchase, see here. New registrations are temporarily suspended until January 16, 2023 to allow priority purchase for our long-term business partners.

Design change

22.8.2022

Dear customers, due to better availability, from 22/08/2022 we deliver all our controllers in slightly different installation boxes, which are functionally completely identical to the original ones, only they are slightly different in design - they do not have the bottom sharp edge. The size of the controller, i.e. the number of modules and other parameters, does not change. The absence of the bottom sharp edge also objectively facilitates the installation of the controller in the switchboard.

End of cooperation with Russia

25.2.2022

Today we ended our cooperation with Russia. No orders from this country are possible and no technical support will be provided. Also, Russian language will be removed from all our future software updates.

MODBUS

The MODBUS protocol is a proven industry standard. It is supported by our WATTrouter M and Mx devices in SLAVE mode, or SERVER, when the given device answers the queries of the superior unit.

The following protocol variants are supported: MODBUS TCP on the Ethernet line and MODBUS RTU on the RS485 line.

An example of such communication is the communication with the program Modbus Poll. We use this program as reference software to verify protocol and data link functionality.

Example of connecting the WATTrouter Mx device with the Modbus Poll program

Setting the communication of the Modbus Poll program with the Wattrouter Mx via the MODBUS TCP protocol:

Setting up data exchange with Wattrouter Mx for periodic reading of input registers 0-31 using function 4:

The main window of the Modbus Poll program during communication via the MODBUS TCP protocol (for correct values of the 32-bit registers, it is necessary to define the appropriate format for 2 adjacent registers - this was not done on this image):

Setting up data exchange with Wattrouter Mx for one-time writing of configuration registers 0-7 using function 16 (this command externally forces the SSR 1 and Relay 1 outputs to switch on):

If you implement communication with other software on a PC, then we recommend that you first test the communication via Modbus Poll (the program can run for free in trial mode) and then implement the MODBUS communication in your software.

In the Modbus Poll program, it is possible to display the data exchange in the Display/Communication window, which can possibly be used to compare the data flows with other software.
